movies vs dvd's

What's the difference? The descriptions didn't make it very obvious to me.

Oh... never mind. Movies are what you've seen, DVD's what you own. Maybe the movies description could be clearer :)

I actually really like the distinction. I have DVDs I haven't watched. Now if I could just DUPLICATE a DVD I owned to the MOVIES I have seen, it would be heaven. Vice versa for MOVIES I have seen to my DVD collection.
